ObjectiveTo determine the role of intracranial pressure (ICP) monitoring in management of patients with severe traumatic brain injury (TBI) admitted to a large level I trauma center in Southern Iran.MethodsThis was a cohort study performed during a 2-year period in a level I trauma center in Southern Iran including all adult patients (>16 years) with severe TBI (Glasgow Coma Scale [GCS] score, 3–8) who underwent ICP monitoring through ventriculostomy. The management was based on the recorded ICP values with threshold of 20 mm Hg. Decompressive craniectomy was performed in patients with intractable intracranial hypertension (persistent ICP ≥25 mm Hg). In unresponsive patients, barbiturate coma was induced. Patients were followed for 6 months and Glasgow Outcome Scale Extended was recorded. The determinants of favorable and unfavorable outcome were also determined.ResultsOverall, we included 248 patients with mean age of 34.6 ± 16.6 years, among whom there were 216 men (87.1%) and 32 women (12.9%). Eighty-five patients (34.2%) had favorable and 163 (65.8%) unfavorable outcomes. Those with favorable outcome had significantly lower age (P = 0.004), higher GCS score on admission (P < 0.001), lower Rotterdam score (P = 0.035), fewer episodes of intracranial hypertension (P < 0.001), and lower maximum recorded ICP (P = 0.041). These factors remained statistically significant after elimination of confounders by multivariate logistic regression model.ConclusionsAge, GCS score on admission, Rotterdam score, intracranial hypertension, and maximum recorded ICP are important determinants of outcome in patients with severe TBI. ICP monitoring assisted us in targeted therapy and management of patients with severe TBI.
